The heating column 36 drives the rotary table 61 to synchronously rotate, the rotary table 61 drives the convex rod 62 to synchronously rotate, the convex rod 62 continuously props against the compression rod 63 to downwards swing when rotating, the compression rod 63 drives the active carbon plate 64 to synchronously swing, and swing filtration is carried out on the film stripping liquid discharged by the U-shaped tube 41 when the active carbon plate 64 swings, so that the film stripping liquid purifying effect is further improved, meanwhile, the liquid is also pushed, and the phenomenon that the film stripping liquid is excessively accumulated at the inlet of the liquid tank 35 to generate back overflow is avoided; meanwhile, when the convex rod 62 rotates, liquid in the liquid tank 35 is stirred, so that uniformity of liquid circulation heating is effectively promoted; the convex club 62 drives the screen 65 to synchronously rotate when rotating, and the screen 65 salvages tiny massive solids in the liquid when rotating, so that the massive solids are prevented from affecting the development effect and simultaneously preventing the liquid outlet at the bottom of the liquid tank 35 from being blocked; the resistance that produces with liquid when otter board 65 rotates makes shell fragment 67 arc shape change shrink, drives the roll briquetting 66 and slides along otter board 65 inner wall synchronization during the shell fragment 67 deformation, relies on the slip roll of roll briquetting 66 to grind cubic solid, thereby prevent that cubic solid from long-term existence adhesion from increasing the later stage clearance degree of difficulty on the inner wall of liquid tank 35, and the bulk solid has also slowed down the mixed speed of the inside liquid of liquid tank 35 simultaneously.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
